红油色泽稳定性研究

Study on the Color Stability of Red Oil

研究了红油在贮藏过程中色泽的变化,探讨了色泽在不同条件下贮藏时稳定性的变化情况和规律,为其贮藏应用提供了合理化建议。结果表明:红油耐光性差,尤其紫外光下褪色严重,建议贮藏时避光保存;抗氧化剂对红油色泽稳定性的影响相对较小;光源颜色对红油色泽稳定性的影响较大,红色光源能够有效减少红油褪色;4℃低温贮藏更有利于保护红油色泽;铝箔包材和红色包材能够有效保护红油色泽,故包装时尽量选择阻隔性能较好或者红色包材对红油类调味料进行保护。

The color changes of red oil during storage are studied,and the stability changes and laws of red oil during storage under different conditions are discussed,which has provided reasonable suggestions for its storage application.The results show that the light resistance of red oil is poor,especially the color fading is serious under ultraviolet light,so it is suggested to store the red oil away from light;the effect of antioxidant on the color stability of red oil is relatively small;the color of light source has a great influence on the color stability of red oil,and the red light source can effectively reduce the color fading of red oil;low temperature storage at 4℃is more beneficial to protect the color of red oil;aluminum foil packaging material and red packaging material can effectively protect the color of red oil,when packaging,try to choose good barrier performance or red packaging material to protect the red oil seasoning.
